Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have received nine R&D 100 Awards in recognition of their significant advancements in science and technology, a press release said. The honorees were recognized in November at the 55th annual R&D 100 Conference, sponsored by R&D Magazine.

The awards, known as the “Oscars of Invention,” honor innovative breakthroughs in materials science, biomedicine, consumer products, and more from academia, industry, and government-sponsored research agencies. This year’s nine honors bring ORNL’s total of R&D 100 awards to 210 since their inception in 1963, the press release said.

ORNL researchers were recognized for the following innovations:

ACMZ Cast Aluminum Alloys were developed by a team of researchers from ORNL with Fiat Chrysler Automobile U.S. and Nemak U.S.A.

ACMZ aluminum alloys are a new class of affordable, lightweight superalloys capable of withstanding temperatures of almost 100-degree Celsius more than current commercial alloys while providing exceptional thermomechanical performance and hot tear resistance.

Common commercial alloys soften rapidly at high temperatures, limiting their use in next-generation vehicles, while other alloys that can withstand elevated temperatures are cost prohibitive and difficult to cast. ACMZ alloys were developed using a suite of atomic-level characterization and computation tools, resulting in a strong, stable, and versatile material capable of withstanding the stressful conditions of next-generation high-efficiency combustion engines, the press release said.

By harnessing the power of quantum mechanics, researchers hope to create quantum computers capable of simulating phenomenon at a scale and speed unthinkable on traditional architectures, an effort of great interest to agencies such as the U.S. Department of Energy tasked with tackling some of the world’s most complex science problems, a press release said.

DOE’s Office of Science has awarded two research teams, each headed by a member of Oak Ridge National Laboratory’s Quantum Information Science Group, more than $10 million over five years to both assess the feasibility of quantum architectures in addressing big science problems and to develop algorithms capable of harnessing the massive power predicted of quantum computing systems. The two projects are intended to work in concert to ensure synergy across DOE’s quantum computing research spectrum and maximize mutual benefits.

ORNL’s Raphael Pooser will oversee an effort titled, “Methods and Interfaces for Quantum Acceleration of Scientific Applications,” part of the larger Quantum Computing Testbed Pathfinder program funded by DOE’s Advanced Scientific Computing Research office. [Read more…]

There has been strong interest in a voluntary separation program that could reduce the workforce at Oak Ridge National Laboratory by up to 350 positions, but the lab still has to review applications and finalize who qualifies, a spokesperson said Wednesday, the deadline to apply.

The laboratory is still in the middle of reviewing the applications and determining who qualifies, said Morgan McCorkle, ORNL communications media manager.

The workforce could be reduced by up to 350 positions through both voluntary and involuntary separations.

“We still expect to use both mechanisms,” McCorkle said.

The 350-position reduction would decrease the workforce of 4,800 employees by about 7.3 percent. The workforce reduction, which is expected to be completed by the end of this year, was announced by ORNL Director Thomas Zacharia in an August 8 email to employees. [Read more…]

A collaboration between the U.S. Department of Energy and the National Nuclear Security Administration has named a new director of the project to build computing systems that are at least 50 times faster than the nation’s most powerful supercomputers in use today—and the new director will be based at Oak Ridge National Laboratory.

The collaborative project is the Exascale Computing Project. It’s a collaboration between DOE’s Office of Science and the NNSA, which is a semi-autonomous agency within DOE.

The new director is Doug Kothe, a 32-year veteran of DOE’s national laboratory system who most recently served in ORNL’s Computing and Computational Sciences Directorate and as the applications development lead for the Exascale Computing Project, or ECP. For the preceding five years, he led the Consortium for Advanced Simulation of Light Water Reactors, DOE’s first Energy Innovation Hub, which uses supercomputers to improve nuclear reactor performance.

Kothe will be ECP director effective October 1. He will replace Paul Messina, who is stepping down after two years to return to Argonne National Laboratory, a press release said. [Read more…]

In a first-of-a-kind experiment, researchers used neutrons to investigate the performance of a new aluminum alloy in a gasoline-powered engine—while the engine was running.

A team from the U.S. Department of Energy’s Oak Ridge National Laboratory worked with industry partners to perform the test, which looked at whether a high-performance alloy that is promising for automotive applications held up under the heat and stress of an internal combustion engine.

Researchers used neutrons to probe a running engine at ORNL’s Spallation Neutron Source, giving them the opportunity to test an aluminum-cerium alloy under operating conditions.

The feat was a first for the Spallation Neutron Source, said Ke An, lead instrument scientist for the facility’s VULCAN instrument.

“This was the first time an internal combustion engine has been run on our diffractometer, and, as far as we know, on any other,” he said. [Read more…]

A team of researchers from Oak Ridge National Laboratory has been awarded nearly $2 million over three years from the U.S. Department of Energy to explore the potential of machine learning in revolutionizing scientific data analysis.

The Advances in Machine Learning to Improve Scientific Discovery at Exascale and Beyond (ASCEND) project aims to use deep learning to assist researchers in making sense of massive datasets produced at the world’s most sophisticated scientific facilities. Deep learning is an area of machine learning that uses artificial neural networks to enable self-learning devices and platforms. The team, led by ORNL’s Thomas Potok, includes Robert Patton, Chris Symons, Steven Young, and Catherine Schuman.

While deep learning has long been used to classify relatively simple data such as photographs, today’s scientific data presents a much greater challenge because of its size and complexity. Deep learning offers the potential to truly change the way in which researchers use massive datasets to solve challenges spanning the scientific spectrum.

For example, neutron scattering data collected at ORNL’s Spallation Neutron Source contain rich scientific information about structure and dynamics of materials under investigation, and deep learning could help researchers better understand the link between experimental data and materials properties.

“This understanding can help scientists build and support new scientific theories, and help to design better materials,” Potok said. [Read more…]

This story was updated at 5 p.m. Aug. 30.

They haven’t agreed on a final budget number, but the Trump administration and the U.S. House and Senate have proposed spending between about $33 million and $52 million in the next fiscal year to continue disposing of uranium-233 waste materials that are stored at Oak Ridge National Laboratory in a building that is the oldest continuously operating nuclear facility in the U.S. Department of Energy complex.

The uranium-233, or U-233, waste is now stored in secure vaults in Building 3019, which was built in the 1940s at ORNL. Removing the waste could allow ORNL to relax its overall security posture, which will reduce costs, eliminate nuclear safety issues, and make the campus more conducive to collaborative science, according to a U.S. Senate Appropriations Committee report published in July.

Some of the waste is from a 1960s research and development test in New York, and it is being shipped to the Nevada National Security Site, a former nuclear weapons proving ground about 65 miles northwest of Las Vegas. In interviews this summer, DOE officials in Oak Ridge declined to discuss the amount of that waste that has been shipped to Nevada or to say how long the shipments might continue. But they are making progress, said Jay Mullis, acting manager of DOE’s Oak Ridge Office of Environmental Management.

Once all of those materials are shipped, the remaining U-233 at ORNL will be treated in “hot cell” facilities across the street from Building 3019, at Building 2026. The DOE’s Oak Ridge Office of Environmental Management owns both buildings.

Mullis said there is other U-233 waste stored in Building 3019, including from glovebox research at ORNL, from reactor plates, and from conglomerate materials. [Read more…]

The workforce reduction of up to 350 positions at Oak Ridge National Laboratory is expected to decrease personnel costs by about $34 million each year, and the lab expects most of those who apply for voluntary separations from the lab to be of retirement age, a spokesperson said Wednesday.

The workforce reduction, which is expected to be completed by the end of this year, was announced by new ORNL Director Thomas Zacharia in a Tuesday morning email to employees.

“From time to time, sustaining our work effectively and efficiently requires the most difficult of decisions, which is to reduce our staff in certain areas of the lab,” Zacharia said in that email.

The lab hopes to reduce its workforce of 4,800 employees by about 7.3 percent (350 positions) using voluntary separations. Involuntary separations will be used if necessary.

On Wednesday, ORNL spokesperson Morgan McCorkle said the lab plans to reduce about 250 overhead positions and 100 research and development jobs. Overhead jobs are those not directly related to research. The research and development staff who will be eligible for voluntary separations are those who charge more than half of their time to overhead accounts or whose program budgets were reduced in fiscal year 2017, McCorkle said.

A specific breakdown of the affected jobs is not yet available. [Read more…]

Oak Ridge National Laboratory will reduce its workforce by up to 350 positions by the end of the calendar year, ORNL Director Thomas Zacharia said in a Tuesday morning email to employees.

The workforce restructuring plan has been proposed by UT-Battelle and approved by the U.S. Department of Energy, Zacharia said. ORNL is DOE’s largest multiprogram science and energy laboratory.

“From time to time, sustaining our work effectively and efficiently requires the most difficult of decisions, which is to reduce our staff in certain areas of the lab,” Zacharia said. “To allow us to provide for our research missions and to allocate resources most productively, the Department of Energy has approved a Workforce Restructuring Plan proposed by UT-Battelle that will reduce ORNL’s workforce by up to 350 positions by the end of the calendar year.”

Zacharia said the reductions will be made primarily among staff who charge to “indirect accounts,” along with some research staff affected by fiscal year 2017 funding who could not be placed elsewhere in the lab.

“By reducing these positions, ORNL will be able to maintain competitive chargeout rates while freeing resources for discretionary investments that will modernize lab infrastructure and maintain core research capabilities in the mission areas assigned to ORNL,” Zacharia said. [Read more…]
